Referring to fig. 2, the present invention provides a stereoscopic image processing method, in an embodiment of the stereoscopic image processing method, the stereoscopic image processing method includes:
step S10, when a interception instruction for a stereoscopic image is detected, the terminal acquires an odd frame picture and an even frame picture in the stereoscopic image according to the interception instruction;
in this embodiment, the stereoscopic image is a three-dimensional stereoscopic image that allows the user to see in one plane using the binocular vision difference and the optical refraction principle of the user. In addition, the terminal (such as a smart tv, a computer, etc.) in this embodiment needs to detect whether the terminal has a stereoscopic glasses (a device for enabling a user to watch stereoscopic images) switching function, determine whether the stereoscopic glasses switch is turned on, and if the on time is longer than 1 minute, then the subsequent stereoscopic image capturing operation can be performed. Or detecting whether the terminal system has a stereoscopic image switching function, namely detecting whether the terminal supports the playing of stereoscopic images, and performing subsequent stereoscopic image interception operation only when the terminal supports the playing of stereoscopic images. When the terminal plays the stereoscopic video for decoding, after receiving the command of intercepting the video program, namely, the intercepting command of intercepting the stereoscopic image in the terminal, the intercepting operation of the stereoscopic image can be started according to the intercepting command. When receiving the intercepting instruction, user information (such as name, family identity, etc.) corresponding to the intercepting instruction is required to be acquired first, so as to detect whether the user has specific authority to perform intercepting operation, etc. The method for acquiring the user information may be to acquire the user information when the user inputs the user information through a remote controller or other terminals, or may be to perform fingerprint identification when the user picks up the remote controller or other terminals, and determine the user information based on the fingerprint identification result. And, the length of the stereoscopic image to be intercepted, for example, 60 seconds, may be included in the intercepting instruction, and the intercepting instruction further includes a film source of the stereoscopic image, for example, determining whether the film source is a shutter or a polarized light, etc.
After the interception instruction is acquired, the terminal can intercept the stereoscopic image according to the interception instruction, and in the process of intercepting the stereoscopic image video frame program, the stereoscopic image video stream being played in the terminal is read, and a buffer area, namely a buffer area I, is arranged in the terminal so as to temporarily store two frame pictures, namely an odd frame picture and an even frame picture, of the read stereoscopic image. It should be noted that, in this embodiment, the stereoscopic image is played in the terminal in a video stream manner, that is, each frame has a certain playing sequence. And new odd frame images and even frame images are continuously acquired in the first buffer area according to the playing sequence of the stereoscopic images, namely the odd frame images and the even frame images in the first buffer area are continuously updated. As shown in fig. 4, the video temporary storage acquiring module stores the first storage space (the first storage area) in which the odd frame picture and the even frame picture to be acquired are stored. The odd frame picture may be a picture of an odd frame obtained when the clipping operation is performed, such as a first frame picture, a third frame picture, and the like. The even frame picture may be a picture of an even frame acquired at the time of the clipping operation, such as a second frame picture, a fourth frame picture, and the like.
Step 20, the terminal extracts odd pixel information in the odd frame picture and even pixel information in the even frame picture to obtain first pixel information, and extracts even pixel information in the odd frame picture and odd pixel information in the even frame picture to obtain second pixel information;
after the terminal obtains the odd frame picture and the even frame picture, a second buffer area (i.e., a second video left-eye data processing storage space) and a third buffer area (i.e., a third video right-eye data processing storage space) as shown in fig. 5 may be further set, that is, corresponding processing is performed on the odd frame picture and the even frame picture in the first buffer area, an odd line and an even line of the odd frame picture, and an odd line and an even line of the even frame are determined, odd pixel information of the odd line and even pixel information of the even line in the odd frame picture are extracted, and the odd pixel information of the odd line and the even pixel information of the even line in the odd frame picture are stored as first pixel information in the second buffer area. Even pixel information of even lines of the odd frame picture and odd pixel information of odd lines of the even frame picture are extracted, and the even pixel information of the even lines of the odd frame picture and the odd pixel information of the odd lines of the even frame picture are stored as second pixel information in the buffer area three. For example, when the odd frame is the first frame and the even frame is the second frame, and the pixel point of each line of each frame is 1280, calculating 1280/2=640, where the 0-630 pixel point of the first line of the first frame may be stored as the odd pixel information of the first frame in the second buffer, and the 640-1280 pixel point of the second line of the second frame may be stored as the even pixel information of the second frame in the second buffer. The 0-630 pixel points of the second row of the first frame picture are used as even pixel information of the first frame picture to be stored in a buffer area III, and the 640-1280 pixel points of the first row of the second frame picture are used as odd pixel information of the second frame picture to be stored in the buffer area III. The odd pixel information may be half of the pixel points of the odd lines of each frame. The even pixel information may be half the pixel points of the even line of each frame. The first pixel information may be a pixel point stored in the second storage area. The second pixel information may be a pixel point stored in the storage area three.
Step S30, the terminal determines left glasses and right glasses corresponding to the stereoscopic image, transmits first pixel information to the left glasses, and transmits second pixel information to the right glasses;
in this embodiment, a storage area four is also created for storing the left glasses (i.e., the left glasses portion) and the right glasses (i.e., the right glasses portion), that is, it is necessary to first determine the stereoscopic glasses corresponding to the terminal where the stereoscopic image is located, the stereoscopic glasses are connected to the terminal in a communication manner, and determine the left glasses and the right glasses in the stereoscopic glasses. And then respectively starting the left glasses and the right glasses according to the second buffer area and the third buffer area, namely starting a left glasses switch when the odd pixel information in the odd frame picture is received in the second buffer area, transmitting the odd pixel information in the odd frame picture to the left glasses, closing the left glasses when the even pixel information in the odd frame picture is received in the third buffer area, starting a right glasses switch, and transmitting the even pixel information in the odd frame picture to the right glasses. And when the buffer area III receives the odd pixel information in the even frame picture, the left glasses are closed, the right glasses switch is started, and the odd pixel information in the even frame picture is transmitted to the right glasses. When the even pixel information in the even frame picture is received in the second buffer area, a left glasses switch is started, a right glasses is closed, and the even pixel information in the even frame picture is transmitted to the left glasses. When the terminal system processes pixels and sends the pixels to the display panel for display, information for controlling glasses is sent to the stereoscopic glasses so as to dynamically switch the left end and the right end of the stereoscopic glasses, and a user can intuitively see stereoscopic images. And as shown in fig. 6, the video left and right glasses switch data processing storage space is four, namely, the left glasses data and the right glasses data are stored in the storage area is four, and different starting time and closing time of the left and right glasses are set according to different odd-even pixels, for example, the left glasses are started for 50ms when odd pixel information in an odd frame picture is detected, the left and right glasses are closed for 45ms when even pixel information in the odd frame picture is detected, the left and right glasses are closed for 45ms when odd pixel information in the even frame picture is detected, and the left and right glasses are started for 50ms when even pixel information in the even frame picture is detected.
Step S40, if a interception stop instruction for the stereoscopic image is received, the terminal generates an intercepted stereoscopic image according to the first pixel information stored in the left glasses and the second pixel information stored in the right glasses, and outputs the intercepted stereoscopic image.
When an interception stop instruction corresponding to the interception instruction is received in the terminal, the terminal can stop the interception operation of the stereoscopic image according to the interception stop instruction. And a truncated stereoscopic image is formed according to the first pixel information acquired by the left glasses and the second pixel information acquired by the right glasses, that is, the playing sequence of the first pixel information and the second pixel information is determined according to the starting time of the left glasses and the starting time of the right glasses, the first pixel information and the second quadrant information are arranged according to the playing sequence to obtain the truncated stereoscopic image, and the truncated stereoscopic image is output, for example, the truncated stereoscopic image is sent to a display interface of a terminal for displaying.
In addition, in order to assist understanding of the present embodiment, to assist understanding of stereoscopic image capturing, the following is exemplified.
For example, if it is required to intercept a stereoscopic image of a stereoscopic image video stream of 1280x720@60hz, when a user presses a stereoscopic video intercept key, and when the terminal receives an intercept instruction, the terminal acquires user information according to the intercept instruction: the mother, time 60s, the current video (i.e. stereoscopic image) film source is the shutter switch. And stereoscopic image interception is performed according to the interception instruction, namely, a second buffer area and a third buffer area can be created, wherein as the pixel point of each frame picture is 1280, 1280/2=640 can be calculated first, 0-639 of the first row in the first frame picture is stored as odd pixel points (namely, odd pixel information of the odd frame picture) in the second buffer area, 640-1280 of the second row in the second frame picture is stored as even pixel information of the second frame picture in the second buffer area, 0-639 of the second row in the first frame picture is stored as even pixel points (namely, even pixel information of the odd frame picture) in the third buffer area, and 640-1280 of the first row in the second frame picture is stored as odd pixel information of the second frame picture in the third buffer area. And the method is to collect different pixel points for different line numbers in the same way for both the odd frame picture (such as the first frame picture) and the even frame picture (such as the second frame picture) so as to achieve the phenomenon of video pixel interleaving. And a buffer area four is created to store the left and right glasses, i.e. when the pixels of the first row of the first frame picture are 0-640, the left glasses are opened for 50ms, and when the pixels are 640-1280, the left glasses are closed for 45ms. The left eye is closed for 45ms at pixels 0-640 of the second frame and opened for 50ms at pixels 640-1280 of the second frame. And stopping intercepting the stereoscopic image when receiving the intercepting stopping instruction, and outputting the intercepted stereoscopic image.
In this embodiment, the odd-numbered frame picture and the even-numbered frame picture of the stereoscopic image are obtained according to the interception instruction, the odd-numbered pixel information in the odd-numbered frame picture and the even-numbered pixel information in the even-numbered frame picture are transmitted to the left glasses as the first pixel information, the even-numbered pixel information in the odd-numbered frame picture and the odd-numbered pixel information in the even-numbered frame picture are transmitted to the right glasses as the second pixel information, so that the intercepted stereoscopic image generates the phenomenon of video pixel interleaving, the stereoscopic effect of the intercepted stereoscopic image is ensured, and when the interception stopping instruction is received, the intercepted stereoscopic image is formed according to the first pixel information obtained by the left glasses and the second pixel information obtained by the right glasses, and is output, thereby avoiding the phenomenon that in the prior art, additional devices are required to record the stereoscopic image, and improving the efficiency and the accuracy of intercepting stereoscopic image video.
Further, on the basis of the first embodiment of the present invention, a second embodiment of the stereoscopic image processing method of the present invention is further provided, where the step S20 of the first embodiment of the present invention is a refinement of the step of extracting, by the terminal, odd pixel information in the odd frame picture and even pixel information in the even frame picture to obtain the first pixel information, including:
and a step a, the terminal extracts odd pixel information of an odd line in an odd frame picture and even pixel information of an even line in an even frame picture, wherein the odd pixel information of the odd line in the odd frame picture and the even pixel information of the even line in the even frame picture are first pixel information.
In this embodiment, after the terminal determines the odd frame picture and the even frame picture, the buffer area two needs to be set, and the odd line in the odd frame picture is determined, and the odd pixel information of the odd line is extracted, for example, the first line 0-630 pixel point of the first frame picture is used as the odd pixel information of the odd line in the odd frame picture. Similarly, the even lines in the even frame need to be determined, and even pixel information of the even lines is extracted, for example, the second lines 640-1280 pixel points of the second frame are used as the even pixel information of the even lines in the even frame. And the odd pixel information of the odd lines in the odd frame picture and the even pixel information of the even lines in the even frame picture are stored as the first pixel information in the second buffer area.
In this embodiment, the terminal extracts the odd pixel information of the odd line in the odd frame picture and the even pixel information of the even line in the even frame picture, and uses the odd pixel information and the even pixel information as the first pixel information, so that the accuracy of the acquired first pixel information is ensured.

Similarly, the odd lines in the even frame need to be determined, and the odd pixel information of the odd lines is extracted, for example, the first lines 640-1280 pixel points of the second frame are used as the even pixel information of the even lines in the even frame. And the even pixel information of the even lines in the odd frame picture and the odd pixel information of the odd lines in the even frame picture are stored as second pixel information in the third buffer area.
In this embodiment, the accuracy of the obtained second pixel information is ensured by extracting the even pixel information of the even line in the odd frame picture and the odd pixel information of the odd line in the even frame picture and using the even pixel information as the second pixel information.
Further, the step of the terminal transmitting the first pixel information to the left glasses includes:

For example, when pixels of the first row of the first frame are 0-640, the left glasses are opened for 50ms, and when pixels are 640-1280, the left glasses are closed for 45ms. The left eye is closed for 45ms at pixels 0-640 of the second frame and opened for 50ms at pixels 640-1280 of the second frame.
